Django Logger not logging but all other loggers work

I have configured my Django application to run in production but I cannot get anything out of the django logger.

The root logger is writing out to file and Azure logging so I can see my elasticsearch and opencensus logs writing fine but nothing is coming out of django.

At the moment I am using INFO level just to see if anything comes out but I'll be adjusting those once I know things are writing out.

logging django python

So, I found the answer was to completely override the default logging and build it from scratch.

Something was happening in the django path I couldn't fathom.

I'd highly recommend this site as it used easier to following descriptions - https://www.webforefront.com/django/setupdjangologging.html
